` 'Application med July 17,

' type wherein an oil reservoir is'supported at one end'of the stoveframe and is adapted toy supply fuel Y to a number of burners mountedbeneath the stove top; and the invention has especial reference to theprovision of an extension top or cover normally positioned over thereservoir but swingable to one side to permit of the withdrawal of thereservoir upwardly Vfrom its support.

The object of the invention is toprovide an advantageous method ofmounting the extension top with reference to the main top of the stovewhereby to permit of the easy operation of the extension top fromOperative to inoperative position and vice versa.

In the drawingswherein I have illustrated a preferred embodiment ofmyinf vention, Figure 1 is a fragmentary side elevation of the endportion of the stove frame embodying the features of my invention. Fig.2 is a fragmentary top plan view partially in section showing the mannerof mounting the extensionY top. Fig. 3 is an underside view of the same.Fig. 4 is a perspective view of the means for swingably supporting theextension top.

Referring to Fig. 1 of the drawings, 1 designates a stove frame having atop 2, 3 isan oil reservoir supported by means of a bracket 4 securedLto* the stove frame in operative association withan oil well 5 whichleads by way ofapipe to the stove burners (not shown). 7 designates theeX- tension top for the reservoir.

The stove frame 1 andthe means for supporting the reservoir 3 withreferencev to the frame may be of any suitable construction andtherefore need not be herein spe-k ciiically described. f The top 2 forthe frame is also of the usual construction and provides a support forthe extension top 7.

The extension top 7 may be made of a width somewhat less than the widthof the stove top, and is mounted at one end of the stove top so as toSwingin a horizontal plane into an inoperative position (dotted linesFig. 2) to one side of-'its operative `10 is substantially triangular inform Specification of Letters Patent. y Ptented Feb, 22 1921.

position, to permit of the' withdrawal of the reservoir 3 from itssupporting means.

The means for thus supporting the eX- tension top 7 preferably'comprisesa bar 8 rlgidly secured upon the underside of the stove top 2 as bymeans of bolts 9 and projecting a substantial distance outwardlyorforwardly from the main top. At its outer end said bar 8 has pivotedthereto as at l1, a hinge member 10, andto the latter the eXe tensiontopis pivoted at 12. Said member Fim 4) and4 may be constructed from asingle sheet of metal bent upon itselfl to form a segmental cavity orsocket 13 vadapted to receive thebar 8. The pivotal connection thelarger or inner end of the member 10 .i

opposite th'ekpivot 11 at thek outer edgeof the socket 13. To form 'alug to rwhich the extension top may be pivoted, the ends of the sheetfrom which `the member 10 isk formed are brought together at this edgeof the member inthe form of arib 14. As shown in Fig. 8, the edge ofthis rib 14`is shaped so as to snugly engage with the downfturned sideange 7 a of the extension top, thusservingas a stop to limit theswinging movement ofthe top 7.

In the operation of swinging the eXten-y slon top into inoperativeposition, the member 10is swung, in the initial movement of the top, ,onits pivot 11 from the position shown in full lines in` Fig.`2, in whichthe bar 8 engages with the inner wall of thek socket 13, to the positionshown in broken lines in said figure when kthe opposite or outer wall ofthe socket engages withvthe opposite edge of the bar 8. In such movementofthe top 7 and member 10v relative to the bar 8,y the pivot912forthetop is swung ythrough an arc described from the pivot 11 as a center andis carried outwardly and laterally from the stove top 2 a sufficientdistance to permity of the free swinging movement of the extension topoutwardly and transversely with reference to the top 2. The continuedswinging movement of the top 7 upon its pivot 12 carries it to theposition shown in broken lines in Fig. 2 tov one side of its `initial oroperative position. In this position of the top 7, the reservoir 3 maybe readily withdrawn upwardly from its support on the frame.

Near the edge of the extension top 7 opposite the hinging connectiontherefonthere may be provided a latch member 15 rigidly secured upon theunderside of the extension top 7 as by means of bolts 16 and `having arearwardly projecting portion 17 adapted to enter a slot 18 formed inthe end flange 2a of the stove top 2. lIhe portion 17 of the latchmember 15 Vmay be bent to form a hump 19 Ifor preventing an accidentalrelease of the extension top 7 from the top 2. When it is desired toswing the top 7 it is only necessary to litt slightly the end thereofcarrying the Alatch member 15 to release the hump 19 from engagementwith the edge of the slot 18, the hinging connection of the top beingsufficiently `liexible to permit or" such lifting movement of the top 7.y

It will be seen that Iliave produced in an oil stove, an extension topmounted in a very practical manner with reference to the main top. Theconstruction is advantageous in that it involves few parts ofsubstantial simplicity, and the operation of swinging the extension topfrom operative to inoperative position and vice versa requires a minimumexpenditure of effort.

y lWhile I have herein illustrated and described the invention withconsiderable particularity, I desire to have it understood that in theinterpretation of the appended claims they are not to be limited exceptas may be necessitated by the state of the prior art.

claim as my invention:

1. An oil stove comprising, in combination, a frame, a reservoir mountedon one end of the :trame and a top for the reservoir swingable inahorizontal plane to a position at one side of the frame to permit ot thewithdrawal of the reservoir.

In an oil stove, the combination with a trame and an oil reservoirsupported at one end of the trame, a top for the reservoir having apivotal connection with the frame, said connection comprising a pivotmovable outwardly and laterally with reference to the frame.

3. In an oil stove, the combination with a frame and an oil reservoirsupported at one end of the trama-.of an extension top for thereservoir, and means for swingably supporting said top-comprising amember pivotally mounted at one end. a substantial distance from theframe and having the extension top pivoted to its opposite end, the lastmentioned pivot being swingable on an arc struck from the firstmentioned pivot whereby to ycarryl said top outwardly and laterally withreference to the frame.

4;. In an oil stove, the combination of a stove top, anv extension top,and means for swingably supporting the extension top to swing in ahorizontal plane outwardly and laterally with reference tothe stove top.

5. In an oil stove, the combination with a main top and an extensiontop, of means for swingably supporting the extension top comprising atriangularly shaped member having a socket therein, a part ired to theVmain top projecting into said socket and pivoted to the outer end ofsaid part whereby to permit said member to swing to a lim-` itedextent'relative to said part, and said extension top `being' pivotallymounted on said member at its larger or inner end.

6. In an oil stove, the combination vwith a main top and an extensiontop, of means for swingably supporting the extension top to swing in ahorizontalplane to one side of its normal or operative position, and alatch member on one top adapted to engage with the other top toreleasably hold the extension top in such normal orpoperative position.

7. In an oil stove, thel combination with a main top and an extensiontop, of means for swingably supporting the extension top so as to permitit to swing horizontally from a position with one edge abutting the endof the main top to a position at one side of its normal position, andvice versa, and means for releasably holding said ertension top in itsnormal position.

8. In an oil stove, the combination with a frame and a reservoirsupported at one end thereof, of an extension top Aforming a cover forsaid reservoir, means providing a movable pivot upon which said cover isadapted to swing horizontally from a position over said reservoir in adirection outwardly as well as. laterally from the iframe7 and means forreleasably holding the cover in its operative position.

In testimony whereof, I have hereunto set my hand.
